At 100k requests Fly.io costs less ($13 vs $25); and still does at 500M requests ($213 vs $1,524). They're different kinds of tool — container platform and paaS — so the prices don't buy the same thing.

What makers say

Makers on using it for hosting, from Product Hunt and Starter Story interviews, each linked to the source. Products with a page of their own and fuller notes first.

On Fly.io
Machines on Fly made it easy to build SSL-secured proxies and backends for keeping cross-internet Pig automations safe and encrypted.
Pig, the makerSep 2026 ↗
Shoutout to @flyDev - Deploying Mascotly globally was seamless thanks to Fly.io. It made it super easy to get our backend up and running close to users with minimal config. Fast, reliable, and developer-friendly - couldn’t ask for more! 🚀🌍
Mascotly, the makerSep 2026 ↗
Fly’s setup process was smooth and intuitive. Hosting APIs globally with minimal configuration was a huge time-saver.

On Render
Simple, predictable deploys for our Node/Express backend with none of the AWS-console overhead. We needed infra that stayed out of our way while we were heads-down on the product.
Compendium, the makerSep 2026 ↗
Render is stable, easy to use, and get started with - ideally for a startup. We considered Railway but we had some issues with it and didn't have the time to work through them.
Agen, the makerSep 2026 ↗
Render made hosting and deployment ridiculously simple. It’s honestly so smooth that we dont use Azure and AWS, even though we still have a bunch of credits sitting there.

Loved and watch-outs

Themes that recur in makers' words and Hacker News comments, each linked to what it summarises.

Fly.io
Most loved
  • Apps deploy close to users around the world with minimal configuration. PH
  • The CLI makes deploys and scaling a single command. PH
  • Pricing is simple and predictable, with small containers costing very little. HNHN 2PH
Watch-outs
  • Its unmanaged Postgres needs manual recovery when nodes fail or run out of memory. HNHN 2
  • Repeated major outages undermine confidence in its stability. HN
On Product Hunt: 5.0★, 27 reviews · mentioned most: easy deployment, developer friendly, CLI
Render
Most loved
  • Connecting a GitHub repo gives automatic deploys without building pipelines. PH
  • TLS, scaling, health checks and zero-downtime deploys work out of the box. PH
  • Teams find it far simpler than AWS or GCP, and one migration from GCP cut costs sharply. PH
Watch-outs
  • It costs much more than a cheap VPS, and per-container pricing pushes people to pack processes together. HNHN 2
On Product Hunt: 5.0★, 79 reviews · mentioned most: easy deployment, simple setup, scalable infrastructure · complaints: not the cheapest option
